TALKING-MACHINE.

Application led .Tune 26,

To all w fiom t may concern:

Be it known that I, CLINTON E. WOODS,

- a citizen of the United States, residing at Vaterbury, in the countyof New Haven and State of Connecticut, have invented a new andv usefulImprovement in Talking-Machines, of which the following is aspecification.

`- rlhis invention relates to talking-machines,- and particularly to themanner of mounting 'theAV Sound-'conveying Varm which supportsy thesound-boxof such machines, and to the manner of assembling certainVassociated` elements of such machines.

Theprincipal object of this invention is to provide new and improvedmeans for mounting the movable sound-conveying arm of a talking-machineso as to allow the usual freedom of movement ofthe sound-boxv carried bysaid arm and to cooperate with said 'arm inproviding a smooth,sound-tight and unobstructed passageway for sound. v

V .Another objectl of` this invention is to provide new Vand improvedmeans for connecting ysaid movable arm to the stationary amplifyingmember or'horn, which means may 'be quickly and easily assembled andtaken apart.

Infthe preferred embodiment of the inventionfthere is provided in atalking-machine the usual supporting deck `mounted in the cabinet in anysuitable manner and having a -suitablylocated circular apertureextending 'conveying arm,there is 'therethrough to permit the passage ofSound from a'sound-conveying arm to an amplifying member or horn. Toform the female member of a swivel joint for said soundprovided aflanged annular plate, of Which the face portion rests' flat upon and issupported by'isaid deck, and the Vflange portion projects down- `wardlythrough the aperture therein to form a tube. f The male member of saidjoint comrises a second annular late havino a tubul) p b larportionextending through said aperture, being journaled in thedownwardly-projecting tube-portion of said first, annular plate andsupported by the face portion thereof. Fromthe `upper face of saidsecond plate, there rises a marginal flange whichvis turned inwardly atits upper end to form a lip to engage the collared base of thesound-conveying arm, which is secured thereto by a suitable hinge.

The invention is susceptible of embodiment in various forms, one ofwhich, for the Specification of Letters Patent.

purpose of illustrating the invention, has been shown in theaccompanying drawings, in which` Figure 1 is a plan view of a sound-box,sound-conveying arm and mounting therefor, in accordance with thisinvention; and Fig. 2 is aside elevation, partly in section, of theSupporting deck, Sound-conveying arm and associated parts of atalking-machine.

Referring now to Fig. 2, there is shown theusual supporting deck 1mounted Vin any usual manner in the talking-machine. A turntable 2,carrying record-tablet 3, is also Shown. Suitably positioned withrespect to the turntable, there is provided an aperture extendingthrough the supporting deck l. vAn annular plate 4 rests on the upperface of thedeck, registering with the aperture therein,v and has adownwardly projecting 'cylindrical or tubular portion 5 fitting snuglywithin said aperture; l

` A second annular plate 7 rests freely upon 'said plate 4, andhas adownwardly-projecting tubular portion 6, fitting freely within of plate7 there rises which is inturned to form a lip 9. The inner edge of thelip 9 is grooved so as to holda gasket 10 which may be of rubber or amarginal flange 8 any usual packing-materia A tubular sound-conveyingarm 12 is provided at its base with a collar 11, which may be integralwith the arm or may be secured thereto in .any suitable manner. Thecollar 11 isV fitted into and yieldingly engaged by the gasketed lip 9.A portion of the flange 8 and lip 9 is cut away to receive an ear 13which may project from the rear of collar 11 as shown in Fig. 1 or fromthe front of said collar and is slidinofl en aUed by shoulders 14 of thecut-aivayy pogrtibn. A pin 15 passes through corresponding holes in theflange 8 and in the ear 13 to provide a sound-conveying horizontal axis,ear 13 and portion 8 forming arm 12 may be swung on a the pin 15,

together a` hinge.

Supported at the outer end of the soundconveying arm 12 in any suitablemanner, as by an elbow 16, there is provided the usual or any desiredform of sound-box 17, here shown as a convertible sound-box equippedwith two Styli, one of which may be the usual reproducing-needle and theother a jewel-point, so that records of any type may From the facecomprising the plate 7 which be played by a Simple adjustment of thesound-box.V

The sound-conveying arm 12 is allowed the necessary' range of movementtoward Y and away'from the recordtablet by the hinge 13, the contactingof its base portion upon the plate 7 serving as a stop to limit itsdownward movement when there is no record tablet to receive the stylus,while its upward movement is limited by the pressure of the gasket 10 onthe collar 11. v Freedom of movement for the arm 12 about a verticalaxis is provided by the swivel joint bears on the plate 4, the tubularportion 6 of which is journaled in the tubular portion 5 thereof. Inorder to decrease the bearing surface of this swivel joint, theunderside of the plate 7 may be countersunk and the inner side of theflange 5 may be countersunk as shown in Fig. 2. To limit the travel ofthe soundbox in a plane parallel to the record tablet,

' the outer edge of the plate 7 may bev recessed to form shoulders18'which Aabut againsta suitable stop as the screw 19, which is set` inthe plate 4.

To secure the neck 20 of the amplifying member or horn in its properposition relative to the deck 1, there is provided a flanged annularplate 23 which registers with the apertures in said deck, and theinneredge of which is countersunk to receive the base .of fthe tube 5 for'facility in assembling.y

To' secure the plates 4 and 23 to theV deck, there are provided screws24 which pass through holes inthe deck, which register vwithcorresponding countersunk holes in the yplate -neck 2O fits snuglywithin the iange 22 of 4 and threads in the plate 23. The

the plate 23 andv is secured thereto in any desiredv manner as by screws21. The upper end of'fthe neck 20 is of the same internalV diameter asthe tube 6 and is set so as to contact evenly with the lower endthereof,

thus providing a smooth passageway for` Y sound.

In assembling the mounting for the soundc'onveying members of thetalking machine, the plate 4 is first set in place onthe Vdeck 1. Theplate 23 to which the neck 20 is held secure is then fitted on the baseof the tube 5. The plates 4 and 23 are then secured to they deck by thescrews 24, adjustment for varying thickness of the deck 1 being allowedby reason ofthe space between the basel of the tube 5 and the face ofthe countersunk portion of the plate 23.' AThe soundconveying arm 1 2 ishlngedto the` plate 7,

Y an upwardly-extending portion o-said tubu- `ginal flange rising fromYsaid second plate .and inturned to loosely enc1rclesa`1dcollar andhaving a cutaway portion to receive saidY Y which is then journaledinthe tube 5. The stop 19 is then screwed inuntil its head rests ontheplate 7 and-the assembling of the mountingis complete. 'While thedetails yof the preferred ernbodiment of the invention have beenVdescribed with much particularity, Vthe invention is not limited to thespecific details shown since these maybe varied within the terms of theappendedA claims, without departing from the spirit of the invention.
